Outbreak of Equine Herpes Virus

You may have seen the recent news stories concerning an outbreak of
Equine Herpes Virus (EHV 1) in Gloucestershire. Two horses have been
shown to have the neurological form of the disease and one the
respiratory form. It appears that others are also showing signs but have
yet to be definitively diagnosed.

Although not a legally notifiable condition, EHV 1 is contagious and
does have the potential to be quite a serious disease. Indeed, the
neurological form can lead to paralysis. In most cases, EHV 1 is spread
via respiratory transmission so wherever horses are brought together
from different yards there is the possibility for the disease to spread
if one of the horses present is affected. For this reason the Heythrop
have very responsibly suspended hunting for a week.

It is important to be aware that the risk of your horse contracting EHV 1 is very small and there is certainly no need to panic.
However, as with any disease, spotting it early is the best thing for
your horse so the BHS felt it would be useful to provide a short
refresher on EHV 1 and its signs. For most people this will just be
precautionary information but the recommendation is that anyone who has
hunted with the Heythrop since 24 January should put their horse into
quarantine for a minimum of 10 days. The same should apply for all
horses on the same yard, even if they have not been hunting.

Although aimed at a different disease (Strangles) our STEPS leaflet provides lots of useful information about quarantining and isolating horses.

Many of the clinical signs of EHV 1 can be confused with other
diseases. A high temperature is a key indicator and it is essential to
monitor the temperature of ‘at risk’ horses. Affected horses will tend
to be disinterested and off their food, as well as showing typical
respiratory disease signs such as coughing and a nasal discharge. If a
horse is affected by the neurological form of the disease you may see
some incoordination or just general ‘wobbliness’.

Should you have any concerns at all that your horse may be affected please contact your vet immediately.

The BHS is part of the group that produces the HBLB Codes of Practice.
There is much helpful information about EHV in the Codes which you can
access here.
